Abstract In this research, we developed a novel photo-stimulation-responsive composite sphere with a semi-interpenetrating polymer network (semi-IPN) structure, synthesized via an alkali gel method, to enhance the efficiency of agrochemicals. Chitosan (CS) serves as the structural matrix and protective shell, with a loading capacity for the plant growth hormone indole-3-butyric acid (IBA) of up to 41.73 μg/mg, effectively controlling the abrupt release of auxin. The incorporation of photothermal detonation nanodiamond (DND) and the photosensitive poly(N-isopropylacrylamide) (PNIPAm) endows the spheres with the ability to respond to light and temperature stimuli, achieving intelligent control over IBA release.
